I’m not much of an authoritarian, so I hesitate to introduce a new Rule. But I think this one will be useful. It came to me during my visit to the Falkland Islands.
Rule: If you want to buy a Range Rover you will do so only after moving to the Falkland Islands where you can then drive it willy-nilly.
Corollary Rule: If you own a Range Rover now you will ship it to the Falkland Islands where someone else can drive it for you. (Subcorollary: Alternatively you can have yourself shipped with your Range Rover to ensure your continued driving pleasure.)
